The bug can be triggered during Episode 29 or Episode 42 when the character Quiet is chosen as a buddy and will corrupt save files across all platforms. According to a post on Konami’s website, developers are working on a patch, but until then players can still choose Quiet as their buddy if they “use the Butterfly Emblem throughout the mission or avoid raising your Bond level with Quiet to MAX during the course of the mission.” Updates on a patch will be released soon.
